I mean, if you look at gaming today, the consoles of this generation pretty much defined the graphics of this era, including PC graphics. So many games were optimized for a certain type and power of graphics that, in a way, we also had a PC gaming renaissance because the graphics tech was so stable. And now, it's looking that it'll be even more stable.
This, so much this. I love the fact that my 3 year old laptop (probably older if you start from the time it was released not when I bought it) still plays all the latest releases just fine. If this continues for the next generation I will be very happy. I figure I'll probably buy a new laptop 2 years after the new consoles are released and be good for another 5 years at least.
